It consists of two main sections: the Users' Guide and the Developers' Guide. The Users' Guide discusses setting up and running the software on the DSLAM Line card. The Developers' Guide provides details of the software to enable modification and further development. 1.2 Target Audience This document has been prepared for all users of PMC-Sierra reference design boards that need to understand the software/firmware running on the DSLAM line cards. To learn more about the Line Card hardware, please refer to "DSLAM Reference Design: Line Card [4]". For an overview of the DSLAM System, please refer to "DSLAM Reference Design: System Design [5]". 1.3 Objectives * * * * * To provide an overview conceptual understanding of the DSLAM line card software components. To document the setup required to run the software. To document the user interface of the software. To document the software design thereby allowing it to be maintained. To direct the user to other task-specific documents. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE 6 RELEASED APPLICATION NOTE PMC-2000504 ISSUE 2 PM7350 S/UNI-DUPLEX DSLAM REFERENCE DESIGN: LINE CARD SOFTWARE MANUAL 2 2.1 USERS' GUIDE Overview The following files are provided: * * * * The source code of the firmware. (See Developers' Guide section for complete list and description.) compile.bat - batch file for compiling and linking the source code. MAIN.OBJ - object file that can be loaded to a BDM (Background Debug Mode) emulator. main.s19 - Motorola S-record file that can be burned into a ROM. 2.2 Setup The DSLAM Line card software is designed to run under two different setups: ROM (Read Only Memory) and BDM (Background Debug Mode). If modification of the source code is not required, ROM setup allows easy setup with minimal hardware. For further development, the BDM setup is recommended. Both setups are described in detail below. 2.2.1 ROM If modification of source code is not required, the ROM setup is used. Figure 1 illustrates a typical configuration for running the firmware in ROM setup. In this case the software is burned into the ROM and the user cannot modify the software. Jumper J25 (ROM/BDM SELECT) should be open for ROM setup. PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE 7 RELEASED APPLICATION NOTE PMC-2000504 ISSUE 2 PM7350 S/UNI-DUPLEX DSLAM REFERENCE DESIGN: LINE CARD SOFTWARE MANUAL Figure 1: Typical User Configuration Development / Host PC Reference Design Card (with ROM) MC68340 Processor Terminal Emulation Software Serial Cable PMCSierra Devices Serial Port The Motorola S-record file provided, "main.s19" can be programmed to the ROM directly and no compiling is required. 2.2.2 BDM Figure 2 illustrates an example test-bench required to test and modify the firmware. Jumper J25 (ROM/BDM SELECT) should be shorted for BDM setup. The firmware may need modification to add extra functionality or implement new services required by the user and user specific application software. The development PC should contain the following development tools: * * Nohau In-Circuit Emulator (or other Background Debug Mode emulator) Introl-C Compiler/Linker (or other suitable C compiler/linker) Figure 2: Development Testbed Development / Host PC Reference Design Card (without ROM) MC68340 Processor Nohau ICE Terminal Emulation Software Serial Cable BDM Debug Port Serial Port PMCSierra Devices PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE 8 RELEASED APPLICATION NOTE PMC-2000504 ISSUE 2 PM7350 S/UNI-DUPLEX DSLAM REFERENCE DESIGN: LINE CARD SOFTWARE MANUAL The next section describes how to compile the source code to load to the Nohau In-Circuit Emulator. Please refer to the Nohau documentation for details on how to load the compiled code. 2.2.3 Compilation In order to compile the source code, Introl-C compiler/linker must be installed in the system and included in the search path. The batch file "compile.bat" is provided and executing it will produce the appropriate object files and Motorola S-record files for BDM and ROM setup. The linker command file "c68.ld" provided is targeted for BDM setup. In order to generate a Motorola S-record file for ROM setup after development with BDM setup, the file "c68.ld" must be modified. The line that reads: let __RAMstart = 0xE000; /* address at which to map RAM */ needs to be modified to: let __RAMstart = 0x100000; /* address at which to map RAM */ 2.2.4 Serial Port connection The user interface for the DSLAM Line Card software is provided by the serial port of the "DSLAM Line Card" reference design card. Typically this port is attached to a terminal via a serial cable. The terminal provides a keyboard interface to enter commands directly, or a terminal emulation program that allows a file of commands to be sent to the serial port. The serial port should be set up to 9600bps, 8 data bits, no parity and 1 stop bit. The serial cable connects the serial port of the host computer to the RJ-45 connector of the Line Card and has the following pin out: DB-9 pin # signal name RJ-45 pin # 1 Not Connected 2 RXD 3 3 TXD 6 4 Not Connected 5 GND 4 6 Not Connected 7 RTS 8 8 CTS 1 9 Not Connected PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE 9 RELEASED APPLICATION NOTE PMC-2000504 ISSUE 2 PM7350 S/UNI-DUPLEX DSLAM REFERENCE DESIGN: LINE CARD SOFTWARE MANUAL 2.3 User Interface The commands are text characters that can be created via a DOS or Windows editor such as notepad, or entered directly at the terminal. Each command must be delimited by the carriage return and line feed characters. These characters are inserted by typing the return key and are not visible within an editor. Blank lines are valid and are ignored by the command parser. Comments may be inserted into a script file by placing the asterisk character in the first column of each line that contains comments. Fields of a command are delimited by an arbitrary number of blank characters (spaces) or tab characters. The fields of a command must be entered in the order specified and as described below: * * * * * A field with no brackets implies that the text is to be typed exactly as shown. <> brackets around a field imply that the textual representation of a number or character string must be entered in the field. [ ] brackets around a field, or fields, imply that the field(s) is optional. { } braces denotes required parameters. | separates parameters that are mutually exclusive 2.3.1 Command Summary The following list of commands are defined in the following sections: * * * * * * * act clear_stat count PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE 10 RELEASED APPLICATION NOTE PMC-2000504 ISSUE 2 PM7350 S/UNI-DUPLEX DSLAM REFERENCE DESIGN: LINE CARD SOFTWARE MANUAL * * * * read 2.3.2 Detailed Command List The following pages provide a detailed summary for each of the commands. 2.3.2.1 act The activate command activates the S/UNI-DUPLEX device for normal operation.
